View Full Version : Is this too much for 1 pump and in 1 loop?
I'm looking to add in 2 EAH 4870's into my loop but I don't know if I have enough heat dissipation in my loop or enough head pressure to handle the amount of blocks.
My current setup is
Heatkiller Rev 3.0 1366
Bloodrage stock NB block
EK dual 5.25 reservoir
Black Ice GT 120
Black Ice GT 240
Swiftech MCP-355 with XSPC top
1/2" OD tubing
with compression fittings.
If it is too much for 1 loop I will probably end up getting the XSPC res/pump combo and pick up another MCR-355, and go with the following loop setups.
4870 Xfire on the 240 rad
i7 + NB on the 120 rad
Any suggestions would be great but keep in mind that I am looking to keep everything internal.

I have 1 pump (355) with two rads ;) as for me one loop is good enough :up:
I have so connected:
Pump -> rat 2x120mm fan -> Rad 3x120MM Fan -> Mof 1 -> Mof 2 -> CPU Block -> Mobo block -> GPU -> Rez.

Lol, I have one MCP355 powering all of the following:
HK3.0
RX240
Feser 360
2x EK GTX285 waterblocks
2x EK mosfet blocks
1x Koolance NB+SB combined R2E block
My load temps are in the early 60s with a Xeon W3520 at 4.2ghz 1.28v during Linpack testing :) Rest of my temps are very good, NB/SB never above 40, in 3dMark Vantage the GPU never gets above 50 deg C. :)
TBH, my flow is pathetic (2500ml/min), but seeing as my temps are all good I am assuming it isn't worth worrying about!

you cant put an i7 and NB on a 120mm rad unless you are leaving it at stock...
Depending on your fan speeds, you might be a little weak in the radiator department once you add two video cards to the loop. But the HK isn't a particularly restrictive block, and the NB block is flat-bottomed, so you've got pumping power to spare.

Oh very good point there Snipe...

Well thats only if I was to go 2 loops, but since the concensus seems to be that it should be fine on 1 loop I won't need to do that.

crossfire + i7 - 3 120's = HOT:flame::explode2::explode2::explode::stop:

It will be fine as a single loop with appropriate fans, high speed/pressure for those rads.

Black Ice GT rads are incredibly bad.

It a single loop, so that means he doesn't only have the 120 cooling the NB and CPU.
How much are you planing on OC'ing everything? What are your load temps now and what fans are you running?
@millertime359
I currently have my 940 @ 3.65 GHz (22x 166) cpu voltage @ +90, vdroop @ +200.
My fluid temp when I play CoD gets to about 31-33 celcius.
I have Scythe Gentle Typhoon 120 mm 1850 RPM fans on my 120 and 240 rads.
@ownage
Any reason that the Black Ice GT are bad?

Not true - the gts 420 beats the monsta with pus-pull fans @ 1000rpm and higher (1000rpm 140mm is very very quiet.)
you MUST have push-pull fans though, very important.

The GTS420 isn't bad, but the older smaller ones are, like the 120 and 240. See the first post, he has the 240 and so do I.
The 120 and 240 SUCK soooo much, I feel raped buying one :( (never understood why 2 years ago people @ XS said these rads where good :shrug:)
